The verdict

Start with the local benchmark for Broomfield County: 6 FEMA declaration records are 41% below the Colorado county mean, even though the count is higher than 3% of counties in the national registry. On FEMA's distinct National Risk Index model, which combines expected loss with vulnerability and resilience, the county ranks safer than 35%.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Broomfield County is led by Riverine Flooding (about $5.9M Expected Annual Loss, Historical Loss Ratio Relatively Low), while Hail carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Broomfield County's hazard record show?

FEMA National Risk Index

FEMA's data shows an elevated National Risk Index composite of 34.7/100 for this county (Very Low rating). Expected Annual Loss comes in at Relatively Low (roughly $17.1M in annualized losses). Social vulnerability (Very Low) and community resilience (Very High) both factor into how that raw exposure plays out on the ground. Among the 18 modeled hazards, Hail carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at an average of 6.3 times per year here, based on 238 historical events on record.

Declaration frequency

The state comparison is the clearest context for Broomfield County's moderate federal record. Its 6 declarations sit 41% below the Colorado county mean, with 1 Major Disaster entries among them. 2 records concern Snowstorm, the file's most frequent incident type. Spread across 17 years, the registry rate is 0.4 per year. FEMA reports authorized programs separately from the DR, EM, and FM codes.

Reading the federal records together

This county has a small entry in FEMA's NFIP paid-claims table: 20 claims and $178.9K paid in total. PlainHazard calls 1-49 claims a light registry record, a label for this dataset rather than a finding that flood exposure is low. A short claims history can also reflect insurance take-up, the period covered, or losses that were never insured.

Start with the state benchmark: a Colorado county averages 10.2 federal declaration records, while Broomfield County has 6. The gap is 41% below that mean. Fewer entries indicate a quieter history of recorded federal actions, not immunity from a hazard and not a prediction about what happens next.

How often does each hazard strike Broomfield County?

FEMA's National Risk Index models a historical event count and an annualized frequency for each hazard type. Most hazards are expressed as modeled occurrences per year; FEMA expresses drought and heat-wave frequency as event-days per year. These modeled frequencies are not forecasts.

Hazard NRI Risk Rating Recurrence
Hail Relatively Moderate an average of 6.3 times per year
Lightning Relatively High an average of 47 times per year
Winter Weather Relatively Moderate an average of 14 times per year
Wildfire Relatively Low roughly once every 1,303 years
Tornado Relatively Low roughly once every 33 years
Strong Wind Relatively Moderate an average of 1.2 times per year
Cold Wave Relatively Low an average of 1.2 times per year
Volcanic Activity Very Low roughly once every 10,000 years
Earthquake Very Low roughly once every 1,645 years
Ice Storm Relatively Low roughly once every 67 years

What Snowstorm declarations mean here

Snowstorm is the most frequent declaration type on Broomfield County's record, 33% of its declarations. Snow-related declarations work on a narrower basis than most other hazards: they are generally issued to reimburse the cost of snow removal and emergency protective measures, rather than to repair destroyed property.

The qualifying test is unusual too. FEMA assesses snowfall against record levels for the affected area, so the same storm total can qualify in a county where it is historically extreme and not qualify a few hundred miles north where it is an ordinary winter. A low snowstorm declaration count is therefore not evidence of mild winters.

Declaration counts describe past federal action. They are a record of what was declared, not a forecast of future hazard probability.

The model's sharpest exposure here: Hail

Hail is among the most expensive hazards in the model relative to how little it threatens life. It concentrates on roofs, vehicles and crops, and a single severe storm can generate an insurance loss across a metropolitan area without a single injury.

Worth noting for Broomfield County: the model and the federal record do NOT point at the same hazard. Hail carries the highest modeled rating (Relatively Moderate), while the county's declaration history is led by Snowstorm. That is not a contradiction, the two measure genuinely different things. Declarations record federal ACTION, which requires damage costly enough to exceed state and local capacity; the Risk Index models EXPECTED annual loss across all 18 hazards whether or not any declaration ever followed. A hazard can be the county's largest modeled exposure and never once have driven a declaration.

National Risk Index ratings are modeled estimates of expected annual loss, not predictions of what will happen in any given year.

Comparisons use published FEMA declaration fields plus the National Risk Index composite for Broomfield County. Record similarity, not a safety rating.

How these peers are chosen

Cohort: Published U.S. county equivalents outside the source state or territory. Each metric keeps six ETL candidates; three unique destinations are shown after de-duplicating across axes. Declaration-volume ranking combines count and Major-disaster share and prefers a different leading incident type; Major-share ranks the Major fraction adjusted for volume; NRI ranks the modeled composite score only.

Data Sources & Methodology

Disaster declaration data comes from the FEMA OpenFEMA Disaster Declarations Summaries v2 API, which includes all federally declared disasters, emergencies, and fire management assistance grants.

Storm event data is sourced from the NOAA Storm Events Database (2015-2025), which tracks significant weather events including thunderstorms, tornadoes, floods, and winter storms.

Flood insurance data comes from the FEMA National Flood Insurance Program (NFIP) OpenFEMA claims dataset.

This data is provided for informational purposes only. FEMA disaster declarations represent federal response actions and may not capture all local emergencies or weather events.

What this means for Broomfield County

Against a Colorado county mean of 10 declarations, Broomfield County, CO records 6, or 41% fewer. PlainHazard classifies that historical total as moderate activity.

  • Emergency is the largest group (5 of 6) in a declaration history that remains below its state benchmark; frequency here is not a forecast. Colorado overview
  • Nationally the county exceeds 3% of recorded county totals, but its own Colorado benchmark is higher. The ranking keeps those two contexts separate. Most-disaster rankings
  • A short NFIP claims file cannot establish low flood exposure; the data guide explains the limits of each federal measure. Disaster-data guide

A below-average federal record is not a safety guarantee. Use National Weather Service alerts and local emergency-management notices for present conditions, not this historical comparison.
